Trying to Backup my system

Hi,

I got Macrium Reflex free version.

1. I created my win8 pro 64bits HD image 029BAD2ABA1011C9-00-00.mrimg

2. Creating recover dvd failed on 4 different CD-Rs & DVD-RWs first on Linux option& gave fail error as Attached

3. Then option MS PE gave same fail error also as Attached.

The disks are perfectly OK & their properties confirm this.

Any reason for above?

I presume the Macrium's Recover disk creates an ISO of the above image?

Is there another way to create same Recovery disk that would go on a CD/DVD?

& is there another free program I could try? ...........thanx .......nick

PS. sorry could not attach scans here
